TROUBLESHOOTING

CONTROL MODULE DESCRIPTION

The purpose of these instructions is to familiarize the reader with the Modular Controls offered
as options with the various models of the SD TF Series Compactors. These options include
the Traction Control, Auto Vibration / Impact Meter Control and the Variable Vibration Control.
One, two or three controls, (1, Figure 6-5) may be mounted in the battery compartment
allowing quick connection and disconnection to the appropriate wiring harness or connection
to a troubleshooting device.
Each control includes the following:
• POWER Green LED (light emitting diode) to indicate, if lit, the machine-mounted
microprocessor is getting electrical power
• SYSTEM Green LED to indicate, if lit, a system check has been made by the
microprocessor and it is operating properly
• MODE Yellow LED which will blink at a fast six-cycles-per-second rate to indicate
software has not been loaded into the control; or blink at a slow, two-cycles-per-
second rate to indicate software has been loaded and no errors have been found by
the microprocessor.
• STATUS Red LED will indicate specific faults by an ON/OFF blinking, four-bit code
with the time ON identified as a short or long flash. The sequence is specific to one
fault only. The code(s) will repeat after a three-second delay.

POWER MUST BE ON

The indicator lights described above will not illuminate it electrical power is eliminated to the
compactor via the ignition key. If this occurs, the compactor must be restarted and driven a
minimum of thirty seconds in one direction at a minimum speed of 0.8 km/h (1/2 mph) per to
allow calibration of the controls and indication of a fault.
Use of the emergency stop will shut down the engine but does not eliminate the power to the
controls therefore the recalibration is not required.
